FILE - This July 7, 2013 file photo shows firefighters watering railway cars the day after a train derailed causing explosions of railway cars carrying crude oil in Lac Megantic, Que. The Obama administration has delayed by nearly a year a plan to boost safety standards for the type of rail car involved in a fiery explosion that killed at least 47 people in Canada this month. Officials began work on the rule more than a year before an oil train derailed and exploded in Quebec July 6, but the rule was never published. (AP Photo/The Canadian Press, Paul Chiasson, File)

In this Friday, July 12, 2013, photo, work continues at the crash site on in Lac-Megantic, Quebec of a train that derailed igniting tanker cars carrying crude oil that killed fifty people. U.S. and Canadian drillers are producing oil faster than new pipelines can be built. As a result, trains have become an unexpected yet vital way to move this bounty of energy from the continent’s midsection to refineries along the coasts. However, since the July 6 tragedy in Lac-Megantic, where a runaway train carrying 72 carloads of crude derailed and killed 50 people, there have been calls for tougher regulations, stronger rail cars and more pipelines.

Firefighters continue to work in Lac Megantic, Quebec July 12, 2013. Police erected an 8-foot (2.5-meter) fence blocking from view what was once a downtown core of restaurants, bars and shops - but which now resembles a blackened warzone after a train pulling 72 cars of crude oil jumped the track and exploded into flames in Lac Megantic on July 6. Some 24 bodies have so far been recovered in the blast zone, police said on Thursday, with another 26 reported missing and presumed dead. REUTERS/Christinne Muschi
